The simplest reason why we wont get a Z.

^ How true.

Tesla knows exactly what it wants to be when it grows up. Whether it gets there or not is definitely up for debate. But Nissan seems incapable of identifying a goal, much less reinventing itself for the 21st century.

Of course, Chevy, Ford, and Dodge are pretty diverse and are even be able to service diverse specialty markets. Light and medium duty pickup trucks, commercial vehicles, electric/hybrids, people movers, sports/muscle cars, and specialty cars. No small feat, that.

The "enthusiast" market is irrelevant in terms of overall size and the share Nissan can command. At least the traditional "enthusiast" market. There is a whole new segment where that term applies, in the early adoption of electrics. This too, will pass once those cars become the norm.

Interestingly, Maserati is rumoured to be going all-electric too. There was talk of it entering a team in Formula E, but honestly I doubt that league will exist long enough (in its present form, anyway) for this to happen.
